Soils are finally stepping into the spotlight of global climate action! They do so for good reasons. Long underestimated, they are now recognised as a pillar for climate mitigation. Yet, let’s be clear: while soils are an emerging hero, they are not a silver bullet. They must complement, not replace, mitigation efforts in energy, transport, industry and other.

May 20–22, 2025 - The Conference "Partners for Change – SOILutions for a Food Secure, Resilient, and Sustainable Future" in Berlin was more than a closing celebration; it was a call to action and a moment of convergence. Over 25 countries came together to chart a bold new course for global soil health. Celebrating a decade of impact, the event called for political leadership, farmer-led solutions, and coordinated action to embed soil health at the heart of sustainable food systems and climate resilience.

The global project ProSoil of Deutsche Gesellschaft für Internationale Zusammenarbeit supports new methods to produce organic fertiliser and new approaches in switching to better and more sustainable cultivating practices in India as well as East and South Africa.

The Ukraine war has brought major disruptions to food and agricultural input supply chains around the globe. The entailing shortages of staple crops, fuel and mineral fertiliser have a direct negative impact on food security in Kenya. This has exacerbated the impact of parallel and previous crises such as the Covid-19 pandemic, droughts and locust invasions, which, all together, have undermined poverty reduction.

Numerous techniques, practices and concepts for soil protection and rehabilitation are being tried and tested globally. Using the project “Soil protection and rehabilitation for food security” as an example, our authors demonstrate what counts in enabling such approaches to unfold impact at scale.

In India, the Green Revolution lifted millions of people out of poverty, yet the large-scale use of chemical fertilisers left the country’s soils severely depleted. ProSoil shows how Indian farmers join traditional and innovative practices to not only restore their soils but also mitigate climate change.

Waste management and soil degradation are two of India’s most pressing environmental concerns. The Indian state of Maharashtra, together with two GIZ projects, tackles both through one market mechanism – ‘city compost’. Urban municipal waste is composted and used as organic fertiliser in agriculture. This relieves the cities’ waste management and enhances rural soils and in turn productivity.
